RANGERS could end up having to play future Champions League games behind closed doors after their fans part in the Romanian riot.

UEFA have launched an enquiry into the trouble which saw punters and stewards clash at half-time in their away visit to Unirea Urziceni.

Officials threatened to abandon the game unless the situation was resolved and UEFA confirmed their delegate Italian Danilo Filacchione had included the ugly clashes in his match report.

The incident has now been referred to UEFA s control and disciplinary committee and they could take heavy action against both teams.

UEFA have a whole range of sanctions from fines and bans to closing grounds open to them.Rangers other problems is they have a string of previous convictions, having been fined for their fans poor behaviour in Villarreal and Osasuna.

A UEFA spokesman said: We have received the match delegate s report and we can confirm that UEFA are now looking into the incidents that occurred during the half-time interval in the Unirea versus Rangers match.’’

I can also confirm that Rangers have been charged with improper conduct for the behaviour of their fans.

‘’ We will continue our investigations and if we can come to a conclusion quickly then the case could be heard and dealt with at our control and disciplinary committee next Thursday.There are a whole range of sanctions that UEFA could take from fines to closing stadiums down or bans.

‘’It all depends on the findings of the committee and the punishment they see fit. ‘’

Unirea could also face action for their part in proceedings.They switched the match to the Steaua Stadium because their own ground wasn t up to scratch.

Rangers officials claim their failure to open the agreed four turnstiles aggravated the situation.Many fans missed the majority of the first half as they got in late.The stewards then had to make more room for the Rangers support and when they moved in to remove flags that was when the trouble started.Frustrated punters were unhappy with the way they were being treated and clashed broke out and some fans were even sprayed with gas and hit by truncheons.

UEFA fined the Light Blues were fined £9,000 for a bus attack against Villarreal in 2006 and were hammered again with a £8,280 fine after clashes with local Spanish police against Osasuna a year later.There were also ugly clashes at the UEFA Cup final in Manchester two years ago although no trouble was taken because the main incidents occurred away from the City of Manchester Stadium.
